describe jurgis's experiences and encounters in the factories.

Jurgis is happy with his job, though he never thought of the “flesh-and-blood side of it” until he works on the killing floor. The pace of the workers is very fast, and Jurgis notices how the bosses hire men that can speed up the pace of the other workers and install those men in crucial positions along the killing lines. This process is “speeding up the gang,” and anyone who cannot keep pace loses his job. Jurgis is dismayed to learn that unlike him, most men in the factory hate their jobs.
